Abstract

MéTODO DE INTER-TRAVAMENTO NA PRESENçA DE COMUNICAçáO E APARATO PARA REDUZIR OU ELIMINAR A INTERFERêNCIA DAS COMUNICAçõES DE RáDIO DE AVIõES. Em um sistema de comunicações de rádio de aeronaves não-limitativo, ilustrativo e exemplificativo, um "ITPC" ("Inter-Travamento na Presença de Comunicação") (50) compreende uni filtro LC passa-baixas duplamente balanceado (52A, 52B) que cobre a faixa de voz. Os sinais de voz vindos de dois VHFs são filtrados e processados por um amplificador (54A, 54B) em um nível adequado para haver detecção de pico. O sinal resultante é aplicado a um amplificador (56) com uma curva de histerese e constante de tempo definidas e finalmente excita o relé (58) do circuito de intertravamento, que inibe um rádio VHF de ACARS de transmitir sempre que outros transceptor de comunicação de VHF a bordo estiverem recebendo sinais de voz. Indicadores visuais provêem informações sobre a operação do sistema e falhas de força (alimentação) do sistema.INTERLOCKING METHOD IN THE PRESENCE OF COMMUNICATION AND APARATO TO REDUCE OR ELIMINATE INTERFERENCE OF AIRCRAFT COMMUNICATIONS. In an illustrative, non-limiting, non-limiting aircraft radio communications system, an "ITPC" ("Communication Presence Interlock") (50) comprises a double-balanced low pass LC filter (52A, 52B) which covers the voice range. Voice signals from two VHFs are filtered and processed by an amplifier (54A, 54B) at a level suitable for peak detection. The resulting signal is applied to an amplifier (56) with a defined hysteresis curve and time constant and finally excites the interlock circuit relay (58), which inhibits an ACARS VHF radio from transmitting whenever other communication transceivers transmit. VHF on board are receiving voice signals. Visual indicators provide information about system operation and system power (power) failures.
